I just bought a 1952 Dodge M37 3.4 ton Cargo Truck yesterday and hauled it home. It only has 22,913 miles. found the service record that same mileage showed up in 1974 service records it still has the original 70 old U S Army truck tires. It has oil in the engine and has not been run since 1974. I probably bought a can of worms but I couldn't pass it up. Now with your video I see something else I need to check. Thanks fo0r the video.
im in a similar spot with my m38 engine and my plan is to use the muriatic acid from home depot and pour about 2-3 gallons into my block like im filling it with coolant and let it dissolve the scale and rust flakes inside as much and as best as it can then start flushing the block like your doing a radiator flushing just without the radiator using a small sump pump and a 5 gallon bucket and just keep repeating the steps till i get mostly clean solution and no chunky bits out of the hoses and then when im happy with it ill use baking soda and water to neutralize the acid and then go from there and when its all reassembled with the radiator ill do a normal flush using the prestone flush stuff
That's encouraging, thanks! I'm gonna do my 50 Plymouth 218 in a week or so. Ordered mine from Midwest also. Seens like a good deal being stainless and including the tool.
You might look into one of the kits sold to clean out old motorcycle gas tanks. It's usually a 3 part process. The first chemical breaks down the old fuel varnish, etc., and cleans down the metal. The second dissolves rust. The final is a sealant, though not desirable in this case. Alternatively, there is a really good product for dissolving rust called Evapo-Rust that really works extremely well. On my m37CDN, I used it and wore out about 20 different brass brushes for cleaning firearms barrels of different gauges and calibers to scrub out the 251 Chrysler, and that seemed to do the trick quite nicely. It's off to the machine shop to be checked for cracks or other issues now, so I'm pretty early in the process to say "I got every last bit", but it sure didn't leave much, if anything.
High concentration of TSP, let sit of half an hour, flush via drain ports. If that sounds a bit to aggressive, use Iron Out in powder form. It does the trick!!!
along this cleaning out one other place crud is stacked up ( mine was 11/2 inchs deep ) the lower freeze plugs take the out pressure wash you will not believe what coms out --rust- to clog up rad. over time next bottom of rad. full of junk (70 yrs ) with rad out flush up side down ---about $250.00 to have rad . rodded out ( took apart and total clean) did not go that rt.
easy way to remove this tube use vice gripes then tap pliers it will break lose and cw out clean it up put back in it cools the valve stems they get very hot
Do you happen to have an installation video for the distribution tube? I'm having a hard time getting mine to go back in after cleaning out everything and I destroyed one trying to get it in. I was only able to get in about 19 in, now need to order a new tube.
Get a copper flexible tube used for an ice maker and attach it to a garden hose driveway sweeper Nozzle. Knock out the freeze plugs and flush the hell out of it
